About

Implement seamless passwordless authentication in your app or website with just a few lines of code. Completely replace your existing authentication flow or build from scratch with a robust solution for passwordless authentication and customer identity management. Realize the full security, business, and user experience benefits of eliminating passwords by offering passkey logins by default with fallbacks to other passwordless methods. Upgrade your existing authentication flow so users have the flexibility to sign in with passkeys or their traditional username and password. Enable your business and customers to begin transitioning to passkeys and proactively prepare for the passwordless future. Migrate your existing users to Passage with a quick import, or build just-in-time provisioning to transition over time.

About

SignOps is a hosted developer API for adding push messaging and sign-in flows to web and mobile applications. Developers can register devices under their existing user IDs, send Android, iOS and web push messages to users or topics, schedule messages, use templates, and review delivery events. The service also provides phone-based login approvals with number matching and biometric confirmation, passkey sign-in on a customer’s domain, TOTP authenticator codes with backup codes, and email one-time passwords. REST endpoints, server SDKs, mobile and web SDKs, a team dashboard, and signed webhooks support integration with an application’s existing backend and identity provider. It is designed for developers and teams building applications that need notifications, passwordless authentication, or additional sign-in verification.
